Rihanna made headlines in Europe for a quick stop at a Swiss hospital as her "Last Girl On Earth" tour continued its global trek – but a rep for the superstar says she's fine.

"She had an injured rib and went to have it looked at to be sure it was nothing serious, and it wasn't," the rep toldAccess Hollywoodon Wednesday. "All is OK and the tour is going great."

MTV News UK first reported that Rihanna was "rushed to a hospital" on Monday night.

A spokesman for the hospital told the site, "The singer Rihanna came yesterday evening to the emergency room. We do not know the details."
